IMPROVEMENT IN ARGAND GAS-BU'RNERS.

Specification forming part of Letters Patent No. 180,336, dated July 25, 1876; application filed May 5, 1876. i

To all whom it may concern Be it known that I, MOSES GALE, of Brooklyn, E: D., county of Kings, and State of New York, have invented certain new and useful Improvements in Argand Gas-Burners, of which the following is a full and exact description, in connection with the accompanying drawings. I

Figurel is a side elevation and partial section of the burner complete. Fig. 2 is aplan or top view. Fig. 3 is a side elevation of the valve shown in Fig. 1.' Fig.5; is a planof the valve-seat in Fig. 1. Fig. 5 isa top view of the valve on its seat. --Figs. 6, 7, 8, 9, 10, and 11 are views of various modifications of valves and seats, as will appear hereinafter in the specification.

This invention pertains to the devices known as the Argand gas-burner, and has for its object chiefly-the proper regulation of the flow of the gas; and therefore it consists, chiefly, in

the combination of the parts that constitute the regulating-valve of the burner and its attachments.

lhe valve itself (shown at A in the several fi gures) is known as the rotating disk-valve, which, by a partial rotation upon its seat, uncovers holes or a port for the escape of the gas to the burner proper, as shown at B, and which may be of any of the well-known or other suit able forms. Said valve is made in the form of a disk, as shown in Figs. 3, 5, 6-, and 7, and'is furnished on its back with a forked stem, as at C, the slit in which is flat on both sides, to receive a secondary stem, for turning it like a key. Said secondary stem is shown at D, Figs. 1 and 9, and upon its outer end is shown the handle, as at E, for turning it, and thereby turning the valve. To prevent the gas from escaping around the outer end of the stem D, it is made with a conical projection or plug, as at F, which projects upward against a seat on the inner face of the valve-chamber, as at G; and between the back of said plug and the back of the valve there is interposeda spiral spring, as at H, which presses the two in opposite directions, and against their seats, as their stems are in separate pieces, and thereby keep both gas-tight when desired. l

The valve shown in Figs. 1 and 3 is a plain disk, with a flat rib on its face wide enough to cover the two holes or ports shown in Fig. 4, which serves as its seat. The object of the disk is to spread the 'gas as it flows to the burner through the valve, to prevent a very common humming noise in such burners.

A modification of such a'valve. is shown in Figs. 6, 7, and 8, where the part that tits on the seat, as at Fig. 4, is perforated with holes to correspond to the holes in the seat when so turned, and the spreading-disk is placed on the stem a little above the valve-face, with a space between them, as at K, Figs. 6 and 8.

Another form of the disk-valve is shown at Figs. 9, l0, and 11, where the face of the valve is slightly convex, and the seat concave, and the two surfaces fit togetherto cover the inlet, as at L in Fig. 9 but when turned'one-quarter round the valve will be fully open, as in Fig.-
